摘要： Following cell death,DNA can be released into the blood plasma and other body fluids in the form of cell-free DNA(cfDNA).These DNA fragments are typically~167 bp in length,corresponding to the length of DNA wrapped around one nucleosome core(147 bp),plus DNA tails that survive endogenous DNase digestion(~10 bp).CfDNA is derived from a variety of sources,each having unique diagnostic applications.During pregnancy,fetal-derived cfDNA within an expectant mother’s blood plasma can diagnose fetal genetic abnormalities and is a well-established method for non-invasive prenatal testing.Cancer-derived cfDNA is also detectable within blood plasma by high sensitivity methods(e.g.,NGS,ddPCR)and can accurately diagnose cancers by a minimally invasive blood test(Diehl et al.,2008).The short half-life of cfDNA(<2 hours)also facilitates real-time measurement of disease burden,such as monitoring cancer relapse.There is now growing evidence of brain-derived cfDNA(bd-cfDNA)within the cerebrospinal fluid(CSF)and blood plasma.In this perspective,we review the present understanding,current challenges,and potential utility of bd-cfDNA.

摘要： Objective:To describe histopathologic findings in the placentas in women with coronavirus disease 2019(COVID-19)during pregnancy.Methods:In a cross-sectional study,38 pregnant women with COVID-19 and undergoing delivery between March 2020 and January 2022,were included.The patients had positive polymerase chain reaction(PCR)test for SARS-CoV-2 infection and the placentas after delivery were sent for histopathologic evaluation based on the Amsterdam Placental Workshop Group Consensus Statement and assessed by two pathologists.Results:Our results showed that maternal vascular malperfusion was the most common and was present in 17 cases(44.7%).These features included accelerated villous maturation(36.8%)distal villous hypoplasia(5.3%),placental infarction(5.3%)and intervillous fibrin deposition(10.5%).Other pathologic findings included focal calcification(10.5%),intravillous congestion and hemorrhage(10.5%),sub-chorionic hemorrhage(5.3%),acute villitis,chronic histiocytic intervillositis and delayed villous maturation each in one case(2.6%).Twelve out of 38 cases showed no significant pathologic changes.Fetal outcomes included neonatal intensive care unit admission rate of 13.2%,dyspnea 31.6%,newborn’s anosmia 7.9%,intrauterine fetal demise 2.6%,asphyxia 2.6%and neonate COVID infection 5.3%.Conclusions:Microvasculopathy,as a sign of maternal vascular malperfusion,is a common finding in placentas from SARS-CoV-2 positive pregnant women in the present study.Further studies with larger sample sizes and comparative studies between COVID-19 positive and negative,as well as information from patient follow-up are suggested.

摘要： THE Economist Intelligence Unit(EIU)circulated the latest version of its Democracy Index on February 10,2022.The title“The China Challenge”reveals much about insecurities of the western world.The EIU,the research and analysis division of The Economist Group,has been producing its much-cited index since 2006 and observes that 2021 was the worst year on record for Westernstyle democracy.Of course,democracy,like beauty,resides in the eye of the beholder.The EIU defines and measures democracy as it is understood in London,near the self-styled“mother of parliaments.”Not surprisingly,therefore,the index suggests that British democracy is 54 percent better than the world average.

摘要： Here the teaching of grammar will be considered in two contexts:that of the foreign language and that of the mother tongue,but precedence will be given to the former.This is not to imply that the latter is unimportant.However,it is simply a fact that there has been more debate,on an international scale,about grammar in foreign language teaching than about the teaching of grammar in the mother tongue setting,in regard to which there is room for many more contributions.
